Landmark CVBD Prevention Field Study Demonstrates Benefits of Advantix(R) Spot-on Treatment for Dogs
a landmark Canine Vector Borne Disease (CVBD) prevention field study,
published in Veterinary Parasitology today, showed the remarkable repelling
efficacy of Advantix(R) in protecting dogs from ticks and sand flies and
thereby reducing the risk of transmission from the potentially deadly
diseases they spread.
This highly comprehensive study, conducted over two years by the team of
degli Studi di Bari)
dogs treated regularly with Advantix(R) spot-on had a greater than 90%
reduction in CVBD cases, including a 100% reduction in new cases of
potentially deadly leishmaniosis and a 94.6% decrease in ehrlichiosis.
The study also found that Advantix(R) provided 97.9% protection against
tick infestation, compared to untreated dogs, where 100% were infested at the
peak of the season. The level of protection offered by Advantix(R) was all
the more notable because of the particularly large numbers of ticks and sand
flies and high prevalence of associated diseases like leishmaniosis or
babesiosis in the area of the study.
According to Prof. Otranto, “Our study shows the importance of protecting
dogs with an effective treatment that repels as well as kills parasites like
ticks and sand flies. Despite the high challenge faced by the dogs in our
study, nearly all our treated dogs remained free from ticks throughout most
of the study, and more than 90% remained free from CVBDs for the whole study
“Because we included naive sentinel beagles in the study, we were also
able to model what would happen to dogs travelling to areas where CVBDs are
present. We found that by the end of the study, only the Advantix(R)-treated
beagles remained protected from infection, while 80% of the untreated beagles
were infected with a CVBD. This demonstrates the very real need to protect
dogs that are travelling to endemic areas”, continued Prof. Otranto.
The study showed some interesting results with dogs that were positive
with CVBDs when they entered the study. Of these, half of those treated with
Advantix(R) were negative for CVBDs at the end of treatment, compared with
only 13% of untreated dogs. This suggests the potential for natural clearance
of CVBDs if a repellent treatment is used to prevent new transmissions.
This study was extremely comprehensive, studying both indigenous and
introduced naive puppies, monitoring for several CVBDs and working with Dr.
Breitschwerdt’s team in the
techniques to ensure optimal diagnostic accuracy. According to Dr.
Breitschwerdt, “This is the most comprehensive study, to my knowledge, ever
conducted testing the efficacy of a repellent ectoparasiticide to prevent the
transmission of a spectrum of CVBDs in young dogs.”
“Thanks to this study we can see just how effective a treatment that
repels as well as kills can be. With the increasing risk of CVBDs, I’d urge
all pet owners to speak to their vets about finding the right tick-prevention
strategy for their dog especially when travelling into endemic areas,” said
leading parasitology expert, Dr.
Tras-os-Montes e Alto Douro,
is important to realise that with globalisation, climate change and the
increase in pet travel, many more pets now need to be protected from these
diseases that can be potentially fatal for both pets and humans. This study
demonstrates that using Advantix(R) is an effective way to protect pets from
bites of ticks and sand flies, reducing the risk of CVBD transmission.

About the study
The study was conducted over two parasite seasons, and ran from
the area and naive sentinel beagle puppies.
A total of 111 indigenous dogs were enrolled alongside 20 naive sentinel
beagles. The dogs were randomly assigned in equal numbers to either a treated
group receiving Advantix(R) at 3-weekly intervals for the course of the study
or a control group receiving no treatment.
Please see the video ‘Prof Otranto – Study design’ for more information
from Prof. Otranto on the study design.
The backgrounder also includes additional information on the study and
